QUESTIONS YOU MIGHT GET FOR CHAPTER 6 ANKLE AND FIBULA

What is the basic positioning routine for a study of the tibia and fibula?

AP and lateral projections

Which ankle projection is best for demonstrating the mortise of the ankle?

AP oblique (15 to 20 degree medial rotation)

The three bones of the ankle form a deep socket into which the talus fits. This socket is called the

Ankle mortise

A small, triangular depression located on the tibia that helps form the distal tibiofibular joint is called the

Fibular notch

Which of the following conditions may cause the tibial tuberosity to be pulled away from the tibial shaft?

Osgood-Schlatter Disease

An inflammatory condition involving the anterior, proximal tibia

Osgood-Schlatter disease

The ankle joint is classified as a synovial joint with -type movement.

Saddle

The distal tibial joint surface forming the roof of the distal ankle joint is called the

Tibial plafond

The articular facets of the proximal tibia are also referred to as the .

Tibial plateau

What is the name of the large prominence located on the midanterior surface of the proximal tibia that serves as a distal attachment for the patellar tendon?

Tibial tuberosity

Why should AP, 45-degree oblique, and lateral ankle radiographs include the proximal metatarsals?

To demonstrate a possible fracture of the fifth metatarsal tuberosity (a common fracture site)

The most proximal aspect of the fibula is the

apex or styloid process

Outward turning or bending of ankle

eversion (valgus)

Inward turning or bending of ankle

inversion (varus)

. The extreme distal end of the fibula forms the

lateral malleolus

Forms an aspect of the ankle joint

talus

Which three bones make up the ankle joint?

talus, tibia, fibula
